Voice coil motor for driving lens

A voice coil motor for driving lens, comprising:

• a housing shell defining a housing space therein and two openings at two ends thereof in communication with the housing space;
• a fixing member fixed in the housing space, the fixing member comprising a bracket defining a through hole therein and a plurality of side retaining spaces in communication with the through hole, and a plurality of coils of wire retained in the side retaining spaces, respectively;
• a movable member movably received in the through hole of the bracket, the movable member comprising a retainer defining a space for receiving the lens, and a plurality of magnetic members mounted on an outer wall of the retainer, each of the magnetic members comprising a first permanent magnet and a second permanent magnet abutting against the first permanent magnet, each of the first and second permanent magnets comprising an N polarity side and an S polarity side, a pair of the first and second permanent magnets facing a same one of the coils of wire with only the N polarity side of the first permanent magnet and only the S polarity side of the second permanent magnet facing the same one of the coils of wire;
• and
• a plurality of elastic members connecting the retainer to the bracket.
